COTERELLUS. Cotarius and Cotrellus, according to Spelman and Du Fresne, are servile tenants; but in Doomsday and other ancient MSS. there appears a distinction, as well in their tenure and quality as in their name; for the cotarius hath a free soccage tenure, and paid a stated firm or rent in provisions or money, with some occasional customary services; whereas the cotrellus seems to have held in mere villenage, and his person, issue, and goods, were disposable at the pleasure of the lord.
